Role of the postinspiratory complex in regulating swallow-breathing coordination and other laryngeal behaviors. | LitMetric

AI Article Synopsis

  • Discoordination between breathing and swallowing can lead to serious issues like aspiration pneumonia, especially in patients with neurodegenerative diseases.
  • Research investigates the postinspiratory complex (PiCo) and how it helps coordinate breathing and swallowing using advanced genetic techniques in mice.
  • Findings show that PiCo activation influences swallowing behavior and laryngeal responses, suggesting it plays a crucial role in maintaining safe airway functions and could help better understand breathing issues in neurological disorders.

Article Abstract

Breathing needs to be tightly coordinated with upper airway behaviors, such as swallowing. Discoordination leads to aspiration pneumonia, the leading cause of death in neurodegenerative disease. Here, we study the role of the postinspiratory complex (PiCo) in coordinating breathing and swallowing. Using optogenetic approaches in freely breathing anesthetized ChATcre:Ai32, Vglut2cre:Ai32 and intersectional recombination of ChATcre:Vglut2FlpO:ChR2 mice reveals PiCo mediates airway protective behaviors. Activation of PiCo during inspiration or the beginning of postinspiration triggers swallow behavior in an all-or-nothing manner, while there is a higher probability for stimulating only laryngeal activation when activated further into expiration. Laryngeal activation is dependent on stimulation duration. Sufficient bilateral PiCo activation is necessary for preserving the physiological swallow motor sequence since activation of only a few PiCo neurons or unilateral activation leads to blurred upper airway behavioral responses. We believe PiCo acts as an interface between the swallow pattern generator and the preBötzinger complex to coordinate swallow and breathing. Investigating PiCo's role in swallow and laryngeal coordination will aid in understanding discoordination with breathing in neurological diseases.
